By choosing By Index Only, you can specify any number of controllers in the Control Index parameter. Otherwise, you can select a controller from the list from this menu. Some controllers have multiple instances, such as Sound Controllers 1-10. Selecting a controller with multiple instances allows you to use the Control Index parameter to select which instances you want. Any invalid control indices will be ignored.\n\n index - Specify the controller by its index, as opposed to specifying a specific type below. n0 - n1 - n2 - n3 - n4 - n5 - n6 - n7 - n8 - n9 - n10 - n11 - n12 - n13 - n14 - n15 - n16 - n17 - n18 - n19 - n20 - n21 - n22 - n23 -\n\n controlind - Used to select controllers by number, or multiple controllers by ranges.

Place a V in the message to specify which value the channel should have.\n\n\n\n\n\n\nThis is similar to other generators' Channel page. However, there are a few points to consider on how they affect the Midi In .\n\n start - Defines where recording begins. In \"Tie to Time Line\" mode, any events received before the start time will be ignored. In \"Time Line Independent\" mode, recording will start at this point and continue on (not looping back). If reading from a MIDI File, Start/End will determine the start of the segment to read. \nStart and end of the interval, expressed in Units (seconds, frames or samples). The parameters are expressed in the Units found on the Common page. To set the to be 100 samples long, Set Units to Samples, Single Off and Start / End to 0 and 99.\n\n\n\n startunit - - Select the units to use for this parameter, Samples, Frames, or Seconds.\n\n samples - Use samples. frames - Use frames. seconds - Use seconds.\n\n end - Defines the end of the segment to read for MIDI Files.\n\n\n\n endunit - - Select the units to use for this parameter, Samples, Frames, or Seconds.\n\n samples - Use samples. frames - Use frames. seconds - Use seconds.\n\n rate - Defines the sample rate of this , in samples per second. If the sample rate is too low, a rapidly changing input may be misrepresented.\t\nNote: If the sample rate is too low, you may miss MIDI events. A note event may set a sample value to 1, and then the next note event less than 1/30 second later can set it to 0 on the same sample in the channel. So the event will be missed. Make the sample rate higher, like 600, to catch these events, or make sure that your on-off events coming in are a minimum time separation, as can be achieved through Opcode's MAX.\n\n\n\n left - - The left extend conditions (before range).\n\n hold - Hold the current value of the channel. slope - Continue the slope before the start of the channel. cycle - Cycle the channel repeatedly. mirror - Cycle the channel repeatedly, mirroring every other cycle. default - Use the constant value specified in the Default Value parameter.\n\n right - - The right extend conditions (after range).\n\n hold - Hold the current value of the channel. slope - Continue the slope after the end of the channel. cycle - Cycle the channel repeatedly. mirror - Cycle the channel repeatedly, mirroring every other cycle. default - Use the constant value specified in the Default Value parameter.\n\n defval - The value used for the Default Value extend condition.\n\n\n\n\n\n timeslice - Turning this on forces the channels to be \"Time Sliced\". A is the time between the last cook frame and the current cook frame.\n\n\n\n scope - To determine which channels get affected, some CHOPs use a string on the Common page.\n\n\n\n srselect - - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or \"Linear\" if the Interpolate Options are not available.\n\n first - Use rate of first input to resample others. max - Resample to the highest sample rate. min - Resample to the lowest sample rate. err - Doesn't accept conflicting sample rates.\n\n exportmethod - - This will determine how to connect the channel to the parameter. Refer to the Export article for more information.\n\n datindex - Uses the docked table and references the channel via the index of the channel in the . datname - Uses the docked table and references the channel via the name of the channel in the . autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.\n\n autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is : are relative to.\n\n\n\n exporttable - The used to hold the export information when using the Table Methods (See above).\n\n\n\n\n\nExtra Information for the MIDI In can be accessed via an Info CHOP.\n\n\n\n - Start of the interval in samples. - Number of samples in the . - The samplerate of the channels in frames per second. - Number of channels in the . - 1 if is enabled, 0 otherwise. - A count of how often the export connections have been updated.\n - Number of times the operator has cooked since the process started. - Duration of the last cook in milliseconds. - Frame number when this operator was last cooked relative to the component timeline. - Frame number when this operator was last cooked relative to the absolute time. - Time in milliseconds at which the operator started cooking in the frame it was cooked. - Time in milliseconds at which the operator finished cooking in the frame it was cooked. - 1 if operator was cooked this frame. - Number of warnings in this operator if any. - Number of errors in this operator if any.\nTouchDesigner Build: Latest\\nwikieditorwikieditorwikieditor2021.100002020.236802020.200002018.28070before 2018.28070\nCHOPs\n• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • \n\nAn Operator Family which operate on Channels (a sequence of numbers (Samples)) which are used for animation, audio, mathematics, simulation, logic, UI construction, and data streamed from/to devices and protocols.\n\n\n\nTOuch Environment file, the file type used by TouchDesigner to save your entire project.\n\n\n\nThe location of an operator within the TouchDesigner environment, for example, /geo1/circle1, a node called circle1 in a component called geo1. The path / is called Root. This path is displayed at the top of every Pane, showing which Component's network you are currently in. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.\n\n\n\nTo \"pulse\" a parameter is to send it a signal from (1) an exported CHOP channel or (2) a python command or (3) a mouse click that causes a new action to occur immediately. A pulse via python is via the .pulse() function on a pulse-type parameter, such as Reset parameter in a Speed CHOP. A pulse from a CHOP is typically a 0 to 1 to 0 signal in an exported channel.\n\n\n\nThe term \"Frame\" is a measurement of time used (1) in the Timeline, (2) as a time-unit in CHOPs, and (3) as a time unit in movie files that are read into TOPs and written out from TOPs. The frame rate is the frames per second (FPS).\n\n\n\nA Time Slice is the time from the last cook frame to the current cook frame. In CHOPs it is the set of short channels that contain the CHOP channels' samples between the last and the current cook frame.\n\n\n\nA parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator. TOPs have Channel Mask, a similar feature.\n\n\n\nA CHOP outputs one or more channels, where a channel is simply a sequence of numbers (Samples), representing motion, audio, etc. Channels are passed between CHOPs in TouchDesigner networks. Channels can be Exported to Parameters.\n\n\n\nA text string that contains data (string, float, list, boolean, etc.) and operators (+ * < etc) that are evaluated by the node's language (python or Tscript) and returns a string, float list or boolean, etc. Expressions are used in parameters, DATs and in scripts.\n\n\n\nEvery operator in TouchDesigner has a set of control Parameters that can be integer or floating point numbers, menus, binary toggles, text strings or operator paths, which determine the output of the operator.\n\n\n\nsamples-per-second of a CHOP. Each CHOP in your network has a sample rate. In contrast, the overall timeline has a Frame Rate, which is the number of frames to cook and display per second, generally your monitor display frequency, default 60.\n\n\n\nExporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.\n\n\n\nAn Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a python Script or GLSL Shader, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.\n\n\n\nTouchDesigner is a hierarchy of components. \"root\" is the top-most network in the hierarchy. The Network Path or Path for root is simply /. A typical path is /project1/moviein1.\n\n\n\n\n\n\n\n\nRetrieved from \"https://docs.derivative.ca/index.php?title=MIDI_In_CHOP&oldid=32288\"\n\t\tCategory: CHOPs", "tooltip": "", "help": "", "units": "", "examples": [], "isReadOnly": false, "isAdvanced": false, "isHidden": false, "isAnimatable": true, "isExpression": false, "isPython": false, "dependsOn": [], "affects": [], "linkedTo": [], "expressionLanguage": "", "defaultExpression": "", "commonExpressions": [], "order": 0, "isVisible": true, "conditionalDisplay": null, "isValid": true, "validationErrors": [], "lastUpdated": "2025-08-07T07:50:04.044Z", "rawData": {}, "sourceElement": null }, { "id": null, "name": "Active", "label": "Active", "group": "General", "page": "", "type": "float", "dataType": "number", "style": "", "defaultValue": null, "minValue": null, "maxValue": null, "step": null, "menuItems": [], "menuLabels": [], "allowCustom": false, "maxLength": null, "pattern": null, "isArray": false, "arraySize": 1, "dimensions": 1, "description": "From Derivative\n\t\t\n\t\t\n\t\t\n\t\t\n\t\tJump to navigation\n\t\tJump to search\n\t\t\nThe MIDI In reads Note events, Controller events, Program Change events, System Exclusive messages and Timing events from both MIDI devices and files.

Any invalid control indices will be ignored.\n\n index - Specify the controller by its index, as opposed to specifying a specific type below. n0 - n1 - n2 - n3 - n4 - n5 - n6 - n7 - n8 - n9 - n10 - n11 - n12 - n13 - n14 - n15 - n16 - n17 - n18 - n19 - n20 - n21 - n22 - n23 -\n\n controlind - Used to select controllers by number, or multiple controllers by ranges. When in By Index Only Controller Type mode, you can select up to the full 128 controllers or sub-ranges thereof (i.e. \"1-10\", \"2 34 70\", \"1-32 70-80:2\").\n\n\n\n format - - Some controllers can be paired together to form 14 bit controllers, rather than the normal 7 bit controllers (controller indices 0-31, 98 and 100). Selecting 14 bit Controllers interprets a pair as one 14 bit controller. Otherwise, they are interpreted as separate 7 bit Controllers.\n\n 7bit - Controllers are assumed to be regular 7 bit value messages. 14bit - Controllers are received as two 7 bit value messages.\n\n norm - - Controller values can be normalized for convenience:\n\n off - When Normalize is Off, 7 bit controllers will return values in the range 0-127 and 14 bit controllers will return values in the range 0-16383. 0to1 - These values are normalized to lie in the range 0 to 1. -1to1 - These values are normalized to lie in the range -1 to +1. onoff - Several of the controllers are simply on/off states. When Convert to On/Off is enabled, values greater than or equal to 64 will be interpreted as \"1\" and all values less than 64 will be interpreted as \"0\".\n\n unwrap - When on, values do not jump between min and max, but are modified to be continuous ramps. Use with knob controllers for examples.\n\n\n\n progname - The name of the Program Change channel. All program change messages will be recorded onto this channel. If blank, this channel will not be created.\n\n\n\n\n\nThe parameters here are only enabled when 'Simplied Output' on the Source Page is Off.\n\n pulsename - Record timer pulse messages.\n\n\n\n rampname - Record timer ramp messages.\n\n\n\n timerperiod - Record timer period messages.\n\n\n\n timerstart - Record timer start messages.\n\n\n\n ticks - Specify the expected ticks per beat.

Place a V in the message to specify which value the channel should have.\n\n\n\n\n\n\nThis is similar to other generators' Channel page. However, there are a few points to consider on how they affect the Midi In .\n\n start - Defines where recording begins. In \"Tie to Time Line\" mode, any events received before the start time will be ignored. In \"Time Line Independent\" mode, recording will start at this point and continue on (not looping back). If reading from a MIDI File, Start/End will determine the start of the segment to read. \nStart and end of the interval, expressed in Units (seconds, frames or samples). The parameters are expressed in the Units found on the Common page. To set the to be 100 samples long, Set Units to Samples, Single Off and Start / End to 0 and 99.\n\n\n\n startunit - - Select the units to use for this parameter, Samples, Frames, or Seconds.\n\n samples - Use samples. frames - Use frames. seconds - Use seconds.\n\n end - Defines the end of the segment to read for MIDI Files.\n\n\n\n endunit - - Select the units to use for this parameter, Samples, Frames, or Seconds.\n\n samples - Use samples. frames - Use frames. seconds - Use seconds.\n\n rate - Defines the sample rate of this , in samples per second. If the sample rate is too low, a rapidly changing input may be misrepresented.\t\nNote: If the sample rate is too low, you may miss MIDI events. A note event may set a sample value to 1, and then the next note event less than 1/30 second later can set it to 0 on the same sample in the channel. So the event will be missed. Make the sample rate higher, like 600, to catch these events, or make sure that your on-off events coming in are a minimum time separation, as can be achieved through Opcode's MAX.\n\n\n\n left - - The left extend conditions (before range).\n\n hold - Hold the current value of the channel. slope - Continue the slope before the start of the channel. cycle - Cycle the channel repeatedly. mirror - Cycle the channel repeatedly, mirroring every other cycle. default - Use the constant value specified in the Default Value parameter.\n\n right - - The right extend conditions (after range).\n\n hold - Hold the current value of the channel. slope - Continue the slope after the end of the channel. cycle - Cycle the channel repeatedly. mirror - Cycle the channel repeatedly, mirroring every other cycle. default - Use the constant value specified in the Default Value parameter.\n\n defval - The value used for the Default Value extend condition.\n\n\n\n\n\n timeslice - Turning this on forces the channels to be \"Time Sliced\". A is the time between the last cook frame and the current cook frame.\n\n\n\n scope - To determine which channels get affected, some CHOPs use a string on the Common page.\n\n\n\n srselect - - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or \"Linear\" if the Interpolate Options are not available.\n\n first - Use rate of first input to resample others. max - Resample to the highest sample rate. min - Resample to the lowest sample rate. err - Doesn't accept conflicting sample rates.\n\n exportmethod - - This will determine how to connect the channel to the parameter. Refer to the Export article for more information.\n\n datindex - Uses the docked table and references the channel via the index of the channel in the . datname - Uses the docked table and references the channel via the name of the channel in the . autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.\n\n autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is : are relative to.\n\n\n\n exporttable - The used to hold the export information when using the Table Methods (See above).\n\n\n\n\n\nExtra Information for the MIDI In can be accessed via an Info CHOP.\n\n\n\n - Start of the interval in samples. - Number of samples in the . - The samplerate of the channels in frames per second. - Number of channels in the . - 1 if is enabled, 0 otherwise. - A count of how often the export connections have been updated.\n - Number of times the operator has cooked since the process started. - Duration of the last cook in milliseconds. - Frame number when this operator was last cooked relative to the component timeline. - Frame number when this operator was last cooked relative to the absolute time. - Time in milliseconds at which the operator started cooking in the frame it was cooked. - Time in milliseconds at which the operator finished cooking in the frame it was cooked. - 1 if operator was cooked this frame. - Number of warnings in this operator if any. - Number of errors in this operator if any.\nTouchDesigner Build: Latest\\nwikieditorwikieditorwikieditor2021.100002020.236802020.200002018.28070before 2018.28070\nCHOPs\n• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • \n\nAn Operator Family which operate on Channels (a sequence of numbers (Samples)) which are used for animation, audio, mathematics, simulation, logic, UI construction, and data streamed from/to devices and protocols.\n\n\n\nTOuch Environment file, the file type used by TouchDesigner to save your entire project.\n\n\n\nThe location of an operator within the TouchDesigner environment, for example, /geo1/circle1, a node called circle1 in a component called geo1. The path / is called Root. This path is displayed at the top of every Pane, showing which Component's network you are currently in. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.\n\n\n\nTo \"pulse\" a parameter is to send it a signal from (1) an exported CHOP channel or (2) a python command or (3) a mouse click that causes a new action to occur immediately. A pulse via python is via the .pulse() function on a pulse-type parameter, such as Reset parameter in a Speed CHOP. A pulse from a CHOP is typically a 0 to 1 to 0 signal in an exported channel.\n\n\n\nThe term \"Frame\" is a measurement of time used (1) in the Timeline, (2) as a time-unit in CHOPs, and (3) as a time unit in movie files that are read into TOPs and written out from TOPs. The frame rate is the frames per second (FPS).\n\n\n\nA Time Slice is the time from the last cook frame to the current cook frame. In CHOPs it is the set of short channels that contain the CHOP channels' samples between the last and the current cook frame.\n\n\n\nA parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator. TOPs have Channel Mask, a similar feature.\n\n\n\nA CHOP outputs one or more channels, where a channel is simply a sequence of numbers (Samples), representing motion, audio, etc. Channels are passed between CHOPs in TouchDesigner networks. Channels can be Exported to Parameters.\n\n\n\nA text string that contains data (string, float, list, boolean, etc.) and operators (+ * < etc) that are evaluated by the node's language (python or Tscript) and returns a string, float list or boolean, etc. Expressions are used in parameters, DATs and in scripts.\n\n\n\nEvery operator in TouchDesigner has a set of control Parameters that can be integer or floating point numbers, menus, binary toggles, text strings or operator paths, which determine the output of the operator.\n\n\n\nsamples-per-second of a CHOP. Each CHOP in your network has a sample rate. In contrast, the overall timeline has a Frame Rate, which is the number of frames to cook and display per second, generally your monitor display frequency, default 60.\n\n\n\nExporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.\n\n\n\nAn Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a python Script or GLSL Shader, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.\n\n\n\nTouchDesigner is a hierarchy of components. \"root\" is the top-most network in the hierarchy. The Network Path or Path for root is simply /. A typical path is /project1/moviein1.\n\n\n\n\n\n\n\n\nRetrieved from \"https://docs.derivative.ca/index.php?title=MIDI_In_CHOP&oldid=32288\"\n\t\tCategory: CHOPs", "tooltip": "", "help": "", "units": "", "examples": [], "isReadOnly": false, "isAdvanced": false, "isHidden": false, "isAnimatable": true, "isExpression": false, "isPython": false, "dependsOn": [], "affects": [], "linkedTo": [], "expressionLanguage": "", "defaultExpression": "", "commonExpressions": [], "order": 0, "isVisible": true, "conditionalDisplay": null, "isValid": true, "validationErrors": [], "lastUpdated": "2025-08-07T07:50:04.048Z", "rawData": {}, "sourceElement": null }, { "id": null, "name": "Active", "label": "Active", "group": "General", "page": "", "type": "float", "dataType": "number", "style": "", "defaultValue": null, "minValue": null, "maxValue": null, "step": null, "menuItems": [], "menuLabels": [], "allowCustom": false, "maxLength": null, "pattern": null, "isArray": false, "arraySize": 1, "dimensions": 1, "description": "The MIDI In reads Note events, Controller events, Program Change events, System Exclusive messages and Timing events from both MIDI devices and files.

Refer to the Export article for more information.\n\n datindex - Uses the docked table and references the channel via the index of the channel in the . datname - Uses the docked table and references the channel via the name of the channel in the . autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.\n\n autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is : are relative to.\n\n\n\n exporttable - The used to hold the export information when using the Table Methods (See above).\n\n\n\n\n\nExtra Information for the MIDI In can be accessed via an Info CHOP.\n\n\n\n - Start of the interval in samples. - Number of samples in the . - The samplerate of the channels in frames per second. - Number of channels in the . - 1 if is enabled, 0 otherwise. - A count of how often the export connections have been updated.\n - Number of times the operator has cooked since the process started. - Duration of the last cook in milliseconds. - Frame number when this operator was last cooked relative to the component timeline. - Frame number when this operator was last cooked relative to the absolute time. - Time in milliseconds at which the operator started cooking in the frame it was cooked. - Time in milliseconds at which the operator finished cooking in the frame it was cooked. - 1 if operator was cooked this frame. - Number of warnings in this operator if any. - Number of errors in this operator if any.\nTouchDesigner Build: Latest\\nwikieditorwikieditorwikieditor2021.100002020.236802020.200002018.28070before 2018.28070\nCHOPs\n• • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • \n\nAn Operator Family which operate on Channels (a sequence of numbers (Samples)) which are used for animation, audio, mathematics, simulation, logic, UI construction, and data streamed from/to devices and protocols.\n\n\n\nTOuch Environment file, the file type used by TouchDesigner to save your entire project.\n\n\n\nThe location of an operator within the TouchDesigner environment, for example, /geo1/circle1, a node called circle1 in a component called geo1. The path / is called Root. This path is displayed at the top of every Pane, showing which Component's network you are currently in. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.\n\n\n\nTo \"pulse\" a parameter is to send it a signal from (1) an exported CHOP channel or (2) a python command or (3) a mouse click that causes a new action to occur immediately. A pulse via python is via the .pulse() function on a pulse-type parameter, such as Reset parameter in a Speed CHOP. A pulse from a CHOP is typically a 0 to 1 to 0 signal in an exported channel.\n\n\n\nThe term \"Frame\" is a measurement of time used (1) in the Timeline, (2) as a time-unit in CHOPs, and (3) as a time unit in movie files that are read into TOPs and written out from TOPs. The frame rate is the frames per second (FPS).\n\n\n\nA Time Slice is the time from the last cook frame to the current cook frame. In CHOPs it is the set of short channels that contain the CHOP channels' samples between the last and the current cook frame.\n\n\n\nA parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator. TOPs have Channel Mask, a similar feature.\n\n\n\nA CHOP outputs one or more channels, where a channel is simply a sequence of numbers (Samples), representing motion, audio, etc. Channels are passed between CHOPs in TouchDesigner networks. Channels can be Exported to Parameters.\n\n\n\nA text string that contains data (string, float, list, boolean, etc.) and operators (+ * < etc) that are evaluated by the node's language (python or Tscript) and returns a string, float list or boolean, etc. Expressions are used in parameters, DATs and in scripts.\n\n\n\nEvery operator in TouchDesigner has a set of control Parameters that can be integer or floating point numbers, menus, binary toggles, text strings or operator paths, which determine the output of the operator.\n\n\n\nsamples-per-second of a CHOP. Each CHOP in your network has a sample rate. In contrast, the overall timeline has a Frame Rate, which is the number of frames to cook and display per second, generally your monitor display frequency, default 60.\n\n\n\nExporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.\n\n\n\nAn Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a python Script or GLSL Shader, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.\n\n\n\nTouchDesigner is a hierarchy of components. \"root\" is the top-most network in the hierarchy. The Network Path or Path for root is simply /. A typical path is /project1/moviein1.\n\n\n\n\n\n\n\n\nRetrieved from \"https://docs.derivative.ca/index.php?title=MIDI_In_CHOP&oldid=32288\"", "tooltip": "", "help": "", "units": "", "examples": [], "isReadOnly": false, "isAdvanced": false, "isHidden": false, "isAnimatable": true, "isExpression": false, "isPython": false, "dependsOn": [], "affects": [], "linkedTo": [], "expressionLanguage": "", "defaultExpression": "", "commonExpressions": [], "order": 0, "isVisible": true, "conditionalDisplay": null, "isValid": true, "validationErrors": [], "lastUpdated": "2025-08-07T07:50:04.051Z", "rawData": {}, "sourceElement": null }, { "id": null, "name": "Active", "label": "Active", "group": "General", "page": "", "type": "float", "dataType": "number", "style": "", "defaultValue": null, "minValue": null, "maxValue": null, "step": null, "menuItems": [], "menuLabels": [], "allowCustom": false, "maxLength": null, "pattern": null, "isArray": false, "arraySize": 1, "dimensions": 1, "description": "active -
